To all 'whom it may concern:

Be it known that I, EMIL WEINHEIM, a citizen of the United States, residing at New York city, in the county andV State of New York, have invented a certain new and useful Improvement in Methods of Producing a Reinforced Resilient Material and the Articles of Manufacture Produced Thereby, of which the following is a specication.

Heretofore resilient materials formed of rubber or its compounds, natural or synthetic resins, gums or balsams, cellulose, and the like, have been reinforced to increase their tensile strength, by forcing the resilient material, while in a fluid, plastic, or semiplastic state, into the body, or into contact with the warp or woof threads or wires of a woven fabric; or alternatively, by covering the surface or surfaces of such resilient material with a woven fabric. This practice, while it serves to increase the tensile strength of the resilient material, lessens the natural resiliency of the material, and does not prevent the wearing or transverse sawing action of the warp and Woof threads or wires upon each other, which is particularly noticeable in bicycle and automobile tires and shoes.

In order to overcome the objections stated, l have devised a new method of treatment and produced a new article of manufacture.

In my improved method, the warp and Woof threads or wires or both of them, are primarily coated wrth a material or materials,

which when treated in the usual manner, as

by the action of chemicals, heating or vulcanizing, form resilient bodies, and such warp or Woof threads or wires or both of them, consolidated by weaving overlying or otherwise, to form a fabric, which fabric if desired, may be given a coating of resilient material on one or more of its surfaces.

The product of my improved method is a material which may be given any desired form, and in which the usual degree of re-` siliency of the material used is not affected, is increased, to correspond to the tensile st en h of the reinforcing threads or wires emp oyed.

The accompanyin drawings will serve to illustrate m invention, in which Figure 1 is a verti section diagrammatiein charactor, and intended to represent' the means employed for applying two coatings of dissimilar resilient material to warp and woof threads or wires, and then drying. Fig. 2 is a similar view, showing the apparatus employed for applying one coating, then chemically acting upon the coating, and then drying. Fig. 3 is a transverse section through one of the drying tanks and illustrates different sections which may be given to the warp and woof threads or wires to be coated and as located in the resilient coating material. Fig. 4 is a vertical elevation and partial section, illustrative of a thread or wire having two resilient coatings. Fig. 5 is a similar view illustrating a thread or wire having one resilient coating. Fig. 6 is a plan view illustrative of a fabric composed of coated and intermingled warp and woof threads or wires. on the line VII- VII of Fig. 6. Fig. 8 is a vertical section corresponding to Figs. 1 and 2, showing the method of applying a single resilient coating and drying. Fig. 9 is a section through a fabric having the warp and Woof threads or wires, covered or interwoven, with surfaces of resilient material.

Referring to the drawings. A indicates a thread or wire to be formed of any suitable material, such as vegetable or animal fiber, a metal or compound, or alloys of metals, and of any cross-section (see Fig. 3) asmay be desired. Surrounding the thread or wire is a covering B (shown as circular in section) which may be applied as a single layer, as shown in= ig. 5,01* as two layers, asshown at B-B in Fig. 4. The covering B may be of any resilient material, such for instance, rubber orV its compounds', natural or synthetic resins, gums and balsams, cellulose, condensation products of phenol and formaldehyde, and the like. I do not limit myself to any particular material. The material may consist of resilient material, or two or more resilient materials; it may be formed of one layer or two or more layers; one of v.these layers may be of high resiliency and the other of lower resiliency. The cross-sec- 1 tion of the covering B may be circular, as

shown,V 01' conform to the crosssect1on of the' thread or wire as `indicated in dotted lines,

Fig. 7 is a section taken method of applying the covering to the thread or wire. The covering may be applied by drawing the thread or wire through a mass of plastlc material, as illustrated at C, Fig. 8, or through separate masses of plastic material as indicated at C and D, Fi 1, or through a mass of plastic materlal and a chemical which coacts with the lastc material, as indicated at C and E, 4ig. 2. In Figs. 1, 2 and 3, the coated thread or wire is shown as carried throu h a drying apparatus indicated at F. As t e character and method of treatment of. the resilient materials above s ecified is well known and forms no part o m invention, I will not enter into any description of the treatment to which such materials are subjected to render them plastic or to harden, dry or vulcanze them.

Instead of appl ing the resilient material as illustrated, by diawing the thread or wire through plastic masses and through a die J of the required size or shape, or through chemical substances and heating and drying ap aratus, I may, in accordance with metho s now known 1n the art, otherwise apply the plastic material, as for instance bg causing the thread or wire to pass t rough rolls disposed to form a plastic mass around the surface of the thread or wire, or by winding the thread or wire with a resilient tape, or otherwise; it being im-` material, so far as my invention is concerned how the plastic resilient material is applied to the thread or wire, so long as the thread or wire is covered.

The thread or Wire, provided with a plastic covering, as above described, is then interwoven to form a fabric, as illustrated in Figs. 6 and 7, where ,G indicates the warp threads or wires, and H the Woof threads or wires. I do not limit myself in any wise to the disposition of the warp and woof threads or wires as re ards' each other; they may be intermingle in any known way. Further, the fabric may consist entirely of one character of covered thread or wire, as for instance woof threads or wires overlying,

^ crossed, mingled, intermixed, or bearin any relation to each other. I have only Illustrated one method of intermiglin threads or wires, z'. e.,Fi 6 and 7 ani estly any arran ement of t eads or wires may be employ Warp or Vwoef threads or wires ma be employed as will be readily under- Y y b s those familiar with the art of producingfabrics. In the drawings I have shown the threads or wires made of a single strand. Manifestly they maybe made up of a number of strands, laced, braided or otherwise. i p

After vproducin the body of the fabric,

as for` instIance wit wa wocfthreeds or wires ma cover e a nc a ing to 'its surfyacesor forcing thrdrnglgpt e fabric having each body thereof, a coating I of resilient ma-V terial, correspondi in resiliency to that alpplied to the threa or wires, or differin t erefrom so far as resiliency 1s concerne It will be seen from the above descrip- 7( tion, that where4 the threads or wires are covered by a resilient material, and are then crossed or otherwise overlie each other, as in weaving, the threads or wires do not come in contact, but only the coverings, which being of resilient material, prevent cutting or sawing of the threads or wires which ive tensile stren to the material. Furt er that as the t reads or wires are embodied in the resilient material, the are not liable to be injured by water, oxi ation, etc.; and owin to the resiliency of the coverings of theA reads or wires, the resiliency o the material as a, whole 1s fpreserved, while the tensile strength of the bric is considerably eater than would be the case if it were ormed wholly of the resilient material.

Having 'thus described my invention, I claim:
